REMOVABLE WIC K -TUBE FOR LAMP-BURNERS.

SPECIFICATION forming part of Letters Patent No. 266,221, dated October 17, 1882.

Application filed April 22, 1882. (No model.)

into a fixed tube ofa lamp-burner, and can be locked in the same by means of a slot in this fixed tube and a stud or projection on the removable tube.

ieference is to be had to the accompanying which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a longitudinal elevation of a lamp-burner provided with my improved removable wick-tube. Fig. 2 is a cross-sectional elevation of the same on the line Fig. 3 is a perspective view of my improved removable wick-tube.

The lamp-burner A, of the usual construction, is provided with a flat tube, B, adapted to receive the removable wick-tube G, which is made of spring-brass or other metal, and is made in the same manner as an ordinary wicktube, but is cut open longitudinally at one edge, so that the flat sides of the tube can be pressed together or separated more or less. The wick-tube O is provided with a series of longitudinal slots,D, through which the ratchet-wheels E of the burner can pass into the wick F. The fixed tube 13 is provided with a recess or slot, G, in its lower end, and the removable wick-tube O is provided with a projection or stud, H, adapted to be passed into the recess or slot Gr for locking the removable wick-tube O in place in the fixed tube 13. When in place in the burner the ends of the removaproject from the ends cess or slot G, as shown in Fig.2, by the spring-v power of the wick-tube G, thereby locking the removable tube 0 in the fixed tube B. A wick can thus be secured in the burner very easily and rapidly.

If the upper end of the wick-tube G is destroyed by heat, a new wick-tube O can be passed into the same burner, and the entire burner is'not made worthless by the destruction of the upper edge of the wick-tube, as is the case in burners provided with fixed wicktubes.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. A removable wick-tube adapted to be locked in a burner and to have its wick independently adjustable therein, substantially as herein shown and described.

2. The combination, with a burner, of a removable wick-tube cut open or split longitudinally, substantially as herein shown and described, and for the purpose set forth.

3. The combination, with the lamp-burner A and the fixed tube B thereof, provided with a recess or slot, G, of the removable wick-tube 0, provided with a stud or projection H, substantially as herein shown and described, and for the purpose set forth.
